We demonstrate a one-pot hydrothermal cohydrolysis-carbonization process using glucose and iron nitrate as starting materials for the fabrication of carbonaceous spheres embedded with oxide nanoparticles. It is verified by TEM, (57)Fe Mossbauer, Fe K-edge XAS that nanoparticles are highly dispersed in spheres, leading to unique microstructure. A formation mechanism also proposed. This route applicable range other naturally occurring saccharides metal nitrates. catalytic study revealed...
Abstract The exfoliation of bulk C 3 N 4 (BCN) into ultrathin layered structure is an effective strategy to boost photocatalytic efficiency by exposing interior active sites and accelerating charge separation transportation. Herein, we report a novel nitrate anion intercalation‐decomposition (NID) that in peeling off BCN few‐layer (fl‐CN) with tailored thickness down bi‐layer. This only involves hydrothermal treatment diluted HNO aqueous solution, followed pyrolysis at various temperatures....
Exploring perovskite oxide electrocatalysts with high activity for the oxygen evolution reaction (OER) is of vital importance various energy conversion processes. Although materials proceeding a lattice oxygen-mediated mechanism-single metal site mechanism (LOM-SMSM) could break inherent theoretical overpotential ceiling absorbent (AEM), fast surface remodeling and loss are still huge obstacles hindering robust electrolysis. Herein, via delicately tuning stoichiometry precursor dosage, we...
A novel Raney Fe@HZSM-5 Fischer–Tropsch synthesis catalyst was synthesized via a facile one-pot strategy using an FeAl alloy as the Fe precursor and Al source. Aside from cracking/isomerization of heavy hydrocarbons, HZSM-5 also stabilizes Hägg carbide, resulting in excellent selectivity to gasoline fraction unexpectedly enhanced C5+ selectivity.
Symmetrical solid oxide electrolysis cells (S-SOECs) have gained attention due to their easier operation. This article reviews the latest achievements of S-SOEC enhance its practical application capabilities.
High-entropy LnBaCo2O5+δ perovskites are explored as rSOC air electrodes, though high configuration entropy (Sconfig) alone poorly correlates with performance due to multifactorial interactions. We systematically engineer (Ln = lanthanides) tunable Sconfig and 20 consistent parameters, employing Bayesian-optimized symbolic regression decode activity descriptors. The model identifies synergistic contributions from Sconfig, ionic radius, electronegativity, enabling screening of 177,100...
A square-planar platinum(II) complex, Pt(DiBrbpy)(C≡CC6H4Et-4)2 (1) (DiBrbpy = 4,4-dibromo-2,2'-bipyridine), and crystals of its three solvated forms, namely, 1·DMSO, 1·1/2(CH3CN), 1·1/8(CH2Cl2), were developed characterized. 1·DMSO 1·1/2(CH3CN) contain quasi-dimeric dimeric structures with luminescence in the visible range, whereas 1·1/8(CH2Cl2) exhibits NIR at 1022 nm due to intrinsic 1-D "platinum wire" stacking structure strong Pt-Pt interactions. represents first compound based on...
The poor temperature activity and durability due to surface Sr segregation are two main challenges restricting the practicability of state-of-the-art La1–xSrxCo1–yFeyO3 (LSCF) air electrodes for solid oxide electrochemical cells (SOCs). This article reports recent discovery unleash constraints performance stability by constructing a novel nanofiber electrode consisting LSCF host GDC guest in nanoscale intertwined moiety (LSCF/GDC NF). electrical conductivity relaxation distribution time...
By means of the rapid quenching (RQ) technique, we fabricate RQ Ni with peculiar undercoordinated site (UCS) abundant and tensile-strained structural characteristics. In liquid-phase CO methanation at 473 K, displays markedly higher specific activity CH4 selectivity in comparison to Raney Ni, supported Al2O3-supported Pd Pt. shows comparable but Ru/Al2O3, Ru being documented as most active metal for methanation. Density functional theory (DFT) calculations confirm that UCSs are centers...
Thermally reduced graphene oxide/carbon nanotube (rGO/CNT) composite films were successfully prepared by a high-temperature annealing process. Their microstructure, thermal conductivity and mechanical properties systematically studied at different temperatures. As the temperature increased, more oxygen-containing functional groups removed from film, percentage of continuously increased. When increased 1100 to 1400 °C, film also 673.9 1052.1 W m-1 K-1. Additionally, Young's modulus was 63.6%,...
Although there is consensus that the optimal safe margin ≥ 5mm, obtaining clear margins (≥5 mm) intraoperatively seems to be major challenge. We applied a molecular diagnostic method at lipidomic level determine surgical resection of OSCC by desorption electrospray ionisation mass spectrometry imaging (DESI-MSI).By overlaying images with hematoxylin-eosin staining (H&E) from 18 recruited participants, spectra all pixels across diagnosed tumour and continuous mucosal regions were extracted...

Various perovskite-type materials have been developed and applied in the field of solid oxide fuel cells (SOFCs). The perovskite oxides prepared by traditional solid-state method usually need to be calcined at a temperature higher than 1000 °C.
